Jury service
Jury service is an important civic duty and an essential part of the criminal justice system. Following the latest government advice and the Lord Chief Justice announcement on 23 March 2020 on jury trials, we’re continuing to review the situation.
New jury trials
We need to make sure everyone in our court buildings are kept safe. This means all new jury trials are currently postponed.
Planning for future jury trials
We do not know when jury trials will start again. We’re continuing to send jury summonses to make sure jurors are available when trials do start again in the future.
If you receive, or have already received a jury summons for a future date, please keep planning to attend court. But do not go to court until we have been in touch. We’ll contact you nearer the time to confirm if you still need to attend.
At that stage, if government advice says you need to self-isolate you will not be expected to start your jury service. You will need to contact the court to let us know if you’re self-isolating or there’s another reason why you cannot attend.
If you have just received a jury summons and need to speak to someone about your personal circumstances, please contact the Jury Central Summoning Bureau on 0300 456 1024. You can also see our general guidance on jury service.
